What are the performance characteristics of lithium ion battery positive and negative materials

The battery cathode material of lithium-ion batteries is one of the important raw materials for determining battery performance, and it is also a key source of the commercialized lithium-ion batteries at this stage. Its characteristics and price are very harmful to rechargeable batteries. At this stage, the key battery cathode materials used for lithium-ion batteries include lithium manganese oxide batteries, lithium cobalt oxide batteries, lithium iron phosphate batteries, and ternary materials. The key battery cathode materials include carbon materials and silicon-based raw materials. The key performance parameters of the positive electrode material of the rechargeable battery include: composition, molecular structure, particle size distribution, tap density, specific surface, PH value, initial charge-discharge specific volume, high efficiency of initial battery charging, and cycle system service life. The characteristics of lithium-ion batteries lie in the structure and characteristics of the internal raw materials of rechargeable batteries, and the characteristics of battery cathode materials more immediately determine the characteristics of rechargeable batteries. Therefore, the battery cathode materials of lithium-ion batteries must consider the basic characteristics of lithium-ion batteries. The development, design and industrial development of lithium-ion battery cathode materials in my country have unparalleled advantages, with a sound entire industry chain and an excellent trend of sustainable development: Ni, Mn are rich in natural resources, and rare metal smelters are technologically perfect. , The positive-level and positive-level precursor industry chain has a complete range. The industry application of rechargeable batteries and battery cathode materials has a large scale of operation, and is actively and rationally arranging recycling and reuse. In recent years, the field of lithium-ion batteries has shown a steady and continuous upward trend, and battery cathode materials have entered an unprecedented opportunity. There are various new materials, and my country and national standards have been continuously published. The negative electrode material of lithium ion battery In the raw material of lithium ion battery, the negative electrode material of the battery is the most important component, which has a greater impact on the overall characteristics of the rechargeable battery. The characteristics of the negative electrode materials of lithium-ion batteries also immediately affect the characteristics of rechargeable batteries, and the cost is about 5 to 15% of that of lithium-ion batteries. Nowadays, battery anode materials are mainly divided into two categories. One is carbon raw materials used for commercial activities, such as pure natural high-purity graphite, soft carbon, etc., and the other is non-carbon materials that have been scientifically developed and designed but have broad industry prospects. Battery cathode materials, such as silicon-based raw materials, alloy products, tin-gold raw materials, etc. Recently, the sales market of lithium-ion battery cathode materials has been operating stably, and sales have improved significantly along with the slow increase in the production and sales rate of the mid- and downstream. The company’s product quotations are relatively stable. At this stage, the price of battery cathode materials in my country is dominated by the low-end and middle-end products, with more than 10,000 yuan per ton for mid-range products, and 70-100,000 yuan per ton for high-end products.
